Israeli soldiers look at the wreckage of an Egyptian military vehicle after militants burst it through a security fence into Israel from Egypt, after it was brought to an Israeli military base along the border with Egypt, southern Israel, Monday, Aug. 6, 2012. Officials say Egypt has deployed at least two helicopter gunships to the Sinai Peninsula in the hunt for militants behind the killing of 16 Egyptian soldiers at a checkpoint along the border with Israel. Suspected Islamists on Sunday evening attacked the Egyptian checkpoint, killed the troops, then stole two of their vehicles and burst through a security fence into Israel. Israeli aircraft then halted their assault. (AP Photo/Tsafrir Abayov)
